the button with the star is for driving on ICE which you will never use in egypt
the other one is the Sport mode of the motor in which the gear transmission occurs at 6000 or more rpm
btw i drove once with the ctivated sports mode with fuel tank to the max and after like 80 km the fuel level dropped to the quarter or even less
but you are gonna enjoy the whole driving experience with such mode
hope i helped you
